The three pressure plates 158 are used to apply pressure to the top of the automobile parts at the same time, which effectively increases the contact area between the pressure plate 158 and the automobile parts, thereby improving the stability of the clamping.

[0033] The contact piece 154 has an arc surface 2 on one side away from the mounting plate 152, a spiral spring No. 1 is arranged between the rotating shaft 157 and the rectangular block 155, and an anti-slip groove is arranged at the bottom of the pressure plate 158.

[0036] A limiting groove is provided on one side of the connecting plate 161 close to the limiting block 169, and the limiting block 169 contacts the inner wall of the limiting groove. The contact piece 154 is limited by the rotating piece 164 to reset, so that the staff can release the limit and take out the automobile parts after observing the drilling situation and performing standard operations.

[0037] When the present embodiment is working, the L-shaped plate 9 contacts with the carrying plate 152 during the downward movement, and the L-shaped plate 9 continues to move to apply downward pressure to the carrying plate 152. The carrying plate 152 moves downward under the action of the pressure, and squeezes the No. 3 spring 153 when the carrying plate 152 moves. The No. 3 spring 153 is squeezed and deformed. At the same time, the movement of the carrying plate 152 drives the contact piece 154 to move downward, and the movement of the carrying plate 152 drives the rectangular block 155 to move downward, and the movement of the rectangular block 155 drives the rotating shaft 157 to move downward, and the movement of the rotating shaft 157 drives the pressing plate 158 to move downward. The anti-skid groove of the pressing plate 158 contacts the top of the automobile part during the movement, and the pressing plate 158 is blocked by the automobile part and stops moving, so that the rotating shaft 157 and the rectangular block 155 stop moving downward, and the carrying plate 152 continues to move to squeeze the No. 4 spring 156. The No. 4 spring 156 is squeezed and deformed. The deformed No. 4 spring 156 applies a downward reaction force to the rectangular block 155 under the action of its own elasticity, and the rectangular block 155 The reaction force is transmitted to the pressure plate 158. The pressure plate 158 is affected by the reaction force and exerts downward pressure on the automobile part, so that the movement of the automobile part is limited. The three pressure plates 158 exert downward pressure on the automobile part at the same time, so as to increase the contact area of ​​the clamping surface, which helps to improve the stability of the clamping. When the top of the automobile part is uneven, one side of the pressure plate 158 contacts the top of the automobile part during the movement, and the contacting side is blocked by the automobile part and stops moving, while the other side continues to move downward to drive the pressure plate 158 to rotate.

The rotating piece 164 stretches the No. 2 scroll spring during the rotation process, and the No. 2 scroll spring is deformed due to the stretching. The deformed No. 2 scroll spring stores energy under the action of its own elasticity. At the same time, the rotating piece 164 separates from the side in contact with the baffle 165 during the rotation process, and the arc surface 2 continues to move and separates from the side in contact with the rotating piece 164. The No. 2 scroll spring recovers and drives the rotating piece 164 to rotate quickly to the initial position. The rotating piece 164 contacts and collides with the baffle 165 during the rotation process. 4 collides with the baffle 165 to generate vibration, and the baffle 165 transmits the vibration to the pressing plate 158.

After the pressing plate 158 stably clamps the automobile part, the operator starts the drilling mechanism 5, and the output end of the driving motor drives the drill bit to rotate. The drill bit contacts the top of the automobile part to drill, and continuous vibration is generated by the intermittent collision between the rotating piece 164 and the baffle 165, and then the vibration is transmitted to the pressing plate 158, which helps to improve the smoothness of the rotation of the pressing plate 158. After the drilling is completed, the linear drive mechanism 3 drives the lifting plate 4 to return to the initial position. When the L-shaped plate 9 is reset, the pressure applied to the carrying plate 152 gradually disappears, and the No. 3 spring 153 recovers to drive the carrying plate 152 to move upward, and the carrying plate 152 drives the contact The sheet 154 moves upward, and the contact sheet 154 contacts the bottom of the rotating sheet 164 during the movement. Since the rotating sheet 164 rotates upward and is blocked by the baffle 165, the rotating sheet 164 blocks the upward movement of the contact sheet 154. The contact sheet 154 stops moving due to the blockage. After observing the drilling situation, the operator manually pushes the push rod 168 to move in the direction of the baffle 165. The movement of the push rod 168 drives the sliding plate 166 to move in the direction of the baffle 165. The sliding plate 166 squeezes the elastic sheet 167 during the movement. The elastic sheet 167 is squeezed and deformed. At the same time, the sliding plate 166 drives the limit block 169 to move in the direction of the baffle 165.

The limit imposed by the C-shaped plate 162 is released, and the push rod 168 is pulled to move in the direction away from the connecting plate 161. The push rod 168 moves to drive the sliding plate 166 to move in the direction away from the connecting plate 161. The sliding plate 166 moves to drive the limit block 169 to move in the direction away from the connecting plate 161. At the same time, the sliding plate 166 moves to drive the C-shaped plate 162 to move in the direction away from the connecting plate 161. The C-shaped plate 162 moves to drive the long round rod 163 and the baffle 165 to move in the direction away from the connecting plate 161. The long round rod 163 moves to drive the rotating piece 164 to move in the direction away from the contact piece 154. The rotating piece 164 separates from the contact piece 154 during the movement, so that the obstruction on the contact piece 154 is released. After the C-shaped plate 162 moves to the specified position,Release the push rod 168, the deformed elastic sheet 167 recovers and drives the sliding plate 166 to move away from the baffle 165. The movement of the sliding plate 166 drives the limit block 169 to move away from the baffle 165. The limit block 169 contacts the inner wall of the limit groove during the movement, so that the movement of the C-shaped plate 162 is limited. The contact sheet 154 is reset by the rotating sheet 164 to limit the staff to remove the limit and take out the auto parts after observation.
